Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stereoscopic image device, and more particularly to a stereoscopic image device for capturing and reproducing a stereoscopic image by using a camera-integrated video.

[0002]

2. Description of the Related Art Conventionally, various devices for photographing, recording and reproducing stereoscopic images have been proposed and implemented. However, when trying to obtain a high quality stereoscopic image, the device tends to be complicated and expensive, while when trying to realize at low cost, the image quality, stereoscopic effect, etc. cannot be sufficiently obtained. was there.

Next, a conventional example of a stereoscopic image device will be described with reference to FIG. In this conventional example, two video cameras are used, and the picked-up images are recorded in one video tape recorder (hereinafter, simply referred to as "VTR") by switching for each field.

FIG. 5 is a schematic block diagram showing the configuration of a conventional example, in which a right video camera 15 and a left video camera 16 for photographing an object 14 to be photographed, a switch 17 for switching a video signal, and the switch 17 are used for switching. From the VTR 18 for sequentially recording the generated signals, the monitor 13b for displaying the reproduced image of the VTR 18, and the right-eye shutter 22 and the left-eye shutter 23 which are opened and closed alternately for viewing the image displayed on the monitor 13b. The liquid crystal glasses 21 and the shutter drive circuit 20 for driving the liquid crystal shutters of the liquid crystal glasses 21 are provided, and the entire system is controlled by the control circuit 19.

First, in photographing and recording of a stereoscopic image by this apparatus, the image pickup object 14 is picked up by the right video camera 15 and the left video camera 16 while being synchronized by the control circuit 19, and the two images are taken. The signal is input to the switch 17, and the control circuit 19 switches the two input video signals for each field, and the VTR 18
Are recorded in sequence. That is, in the NTSC system, the signal captured by the right video camera 15 and the video signal captured by the left video camera 16 are alternately recorded every 1/60 seconds.

Next, the reproduction of a stereoscopic image will be described. The VTR 18 reproduces and displays it on the monitor 13b. At this time, the control circuit 19 extracts the vertical synchronization signal from the reproduction signal of the VTR 18 and the right video camera 15 also.
It is determined whether the signal is captured by the camera or the signal captured by the left video camera 16, and the result is input to the shutter drive circuit 20, and the right eye shutter 22 and the left eye shutter 23 that form the liquid crystal glasses 21 are determined. Open and close. That is, while the field signal captured by the right video camera 15 is being reproduced and displayed, the right eye shutter 22 is set in the light transmitting state, the left eye shutter 23 is set in the non-light transmitting state, and the left video camera is set. When the field signal photographed in 16 is being reproduced and displayed, the left-eye shutter 23 is set to the light transmission state, and the right-eye shutter 22 is set to the light non-transmission state.

According to the above-described method, the right image displayed on the monitor 13b by the right video camera 15 is viewed by the right eye through the right eye shutter 22, while the left video camera 16 is used. The photographed left image is viewed by the left eye through the left eye shutter 23, and the displayed image is sensed stereoscopically.

However, in the stereoscopic image apparatus of the above-mentioned method, the left and right images are switched for each field, so that flicker is conspicuous, and if there is a white moving object on a dark background, an afterimage may be conspicuous. Furthermore, when the tape recorded by the above-mentioned method is reproduced by a VTR and output to a normal monitor, the left and right images are displayed in an overlapping manner and cannot be used normally except for stereoscopic viewing. Furthermore, it becomes a large-scale system configuration,
In addition to being expensive, the operation is extremely complicated, limiting its widespread use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.

First Embodiment A first embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 shows a system configuration for stereoscopic video recording according to the first embodiment, in which a right camera-integrated video 1 and a left camera-integrated video 2 equipped with a display device are directed toward an object to be photographed and fixed on a fixing plate 3. Fixed to. Right camera integrated video 1
Is for obtaining the right image, and the left camera-integrated video 2 is for obtaining the left image. It is desirable to operate the two videos at the same time, which is the remote controller 9
Can be connected to two videos or emit infrared light toward the two videos.

Next, FIG. 2 shows the structure of a stereoscopic image reproduction system, in which the display device for the right camera-integrated video 1 is the right monitor 4 and the display device for the left camera-integrated video 2 is the left monitor 5. , The right image is reproduced on the right monitor 4, and the left image is reproduced on the left monitor 5 in synchronization with each other. It is desirable to use the remote controller 9 for synchronization as in the case of recording. For example, by determining the reproduction positions of both recording tapes with a tape counter and then starting reproduction at the same time, synchronization can be ensured. it can. However, it is general that the two units do not start the simultaneous reproduction strictly, and a slight deviation occurs, but in the method according to the present invention, this slight deviation does not pose a problem. . The term "synchronization" here means that the temporal synchronisms of the recorded images are made to substantially coincide with each other, and does not mean that the vertical or horizontal synchronization signals are completely coincident.

The image displayed on the right monitor 4 is the right eye, and the image displayed on the left monitor 5 is the left eye.
A hood 10 is provided across the two monitors, each for a completely separate lead. The structure of the hood 10 has a shielding plate 10a at the center to separate the left and right optical paths, and except for the surface that comes into contact with the monitor, the side surfaces thereof are covered with a light-shielding member, and the surface that comes into contact with the monitor is opposite. The right eye hole 11 and the left eye hole 12 are provided on the surface corresponding to the left and right optical paths separated. The right eye in the right eye hole 11,
In addition, the stereoscopic image is sensed by putting the left eye on the left eye hole 12 and viewing the reproduced image.

Further, the audio information of the right image from the audio terminal 63 of the right camera integrated video 1 is transmitted to the right ear vibrating part 61 of the headphone 6 via the right cord 7, and the left camera integrated video 2 is also provided. The audio information of the left image is input to the right ear vibrating portion 62 of the headphones 6 from the audio terminal 64 via the left cord 8 to obtain a stereoscopic image together with a stereoscopic image.

The camera-integrated video provided with the display device is a device in which a small video camera, a video recording / reproducing device, and an image display device (for example, a liquid crystal monitor) are integrally configured. For example, there is a product name CCD-SC9 or CCD-SC7 manufactured by Sony Corporation.

Second Embodiment Next, a second embodiment will be described with reference to FIG. FIG. 3 shows a configuration of a stereoscopic video reproduction system according to the second embodiment. The stereoscopic video recording method is the same as the recording method according to the first embodiment, and the description of the recording method here is omitted.

The right VTR 32 is a video tape on which a stereoscopic image created by the method described in the first embodiment is recorded.
And the left VTR 33 reproduce in synchronization with each other. This also adjusts the tape reproduction position by the remote controller 30 as described above, and starts reproduction at the same time. However, as in the first embodiment, two units do not always start simultaneous reproduction exactly, and it is general that a slight deviation occurs. However, in this method, this slight deviation is caused by the monitor 13a described later.
Adjusted by the function built into the, does not matter. The term "synchronization" here means that the temporal synchronisms of the recorded images are made to substantially coincide with each other, and does not mean that the vertical or horizontal synchronization signals are completely coincident. Further, it goes without saying that the playback device may use the right camera-integrated video 1 and the left camera-integrated video 2.

The right VTR 32 and the left VTR 33
The signal reproduced by is input to a monitor 13a having a function of dividing and displaying an image, and a right image is displayed on the right half of the screen of the monitor 13a and a left image is displayed on the left half to display the hood 10. It is used to obtain a stereoscopic image.
The form of the hood 10 is the same as that described in the first embodiment. As a monitor having a function of dividing and displaying an image, for example, there is a product name KV28ST92P manufactured by Sony Corporation.

Third Embodiment Further, a third embodiment will be described with reference to FIG. FIG. 4 shows the configuration of a stereoscopic video reproducing system according to the third embodiment, and the stereoscopic video recording method is the same as the recording method according to the first embodiment, and the description of the recording method here is omitted.

The right VTR 32 is a video tape on which a stereoscopic image created by the method described in the first embodiment is recorded.
And the left VTR 33 reproduce in synchronization with each other. Also, the controller 31 adjusts the reproduction position of the tape to perform simultaneous reproduction. However, also in this case, the two units do not start simultaneous reproduction exactly, and a slight deviation occurs. Note that the synchronization here means that the temporal simultaneity of the recorded images is substantially matched, as already described in the first and second embodiments, and it means that the vertical or horizontal synchronization signals are completely matched. is not. Strict synchronization coincides with the circuit provided in the subsequent stage. Further, it goes without saying that the playback device may use the right camera-integrated video 1 and the left camera-integrated video 2.

Next, the image signal R reproduced by the right VTR 32 is input to the right video memory 34, and the image signal L reproduced by the left VTR 33 is input to the left video memory 35. By synchronizing the read timings of the two, the synchronization of both image signals R ′ and L ′ is matched. The image signals R'and L'are input to the switch 36, and the image is displayed in each field (for example, NTSC).
If it is 1/60 second, it is switched to monitor 13
It is input to b and displayed. That is, the right image and the left image are displayed alternately, and this image is displayed on the liquid crystal glasses 2
The first right-eye shutter 22 and the left-eye shutter 23 are operated in synchronism with the display image to detect a stereoscopic image. Each of these blocks is unified and controlled by the controller 31.

It is needless to say that the shutter member is not limited to the liquid crystal and, for example, a ferroelectric member may be used.

[0031]

As described above, since a video recording tape for stereoscopic vision is created and reproduced by using two video cameras integrated with a camera, a stereoscopic video apparatus which is easy to operate, small in size, and inexpensive can be realized.

Also, by inputting the respective right and left tape reproducing devices corresponding to the right and left vibrating parts of the headphones, it is possible to listen to a stereoscopic sound while viewing a stereoscopic image.

Further, even tapes recorded for stereoscopic viewing are recorded in accordance with normal standards, so that they can be normally displayed and viewed even when connected to a general television.
